MARY E. ROBINSON, OF JACKSON, MISSISSIPPI.

' IMPROVEMENT IN STARCH LUBRICANTS.

Spccification forming part of Letters Patent No. 163,809, dated May 25,1875; application filed March 27, 1875.

To all whom it may concern.-

Be it known that I, MARY E. ROBINSON, of Jackson, in the county of Hindsand State of Mississippi, have invented a new and valuable Improvementin Starch Lubricants; and I do hereby declare that the following is afull, clear, and exact description of the same.

This invention relates to that class of compounds which are used forstarching,1ubricat ing, and giving luster in the process of ironing orsmoothing textile fabrics; and the nature of my invention consists inthe employment of soap to be mixed with the starch, said soap having thesame color as the fabric to be ironed, whereby the color of the latterwill be heightened, as hereinafter more fully set forth.

To prepare the starch compound, I take a quantity of starch of any kind,provided the quality be good, and dissolve the same in water, using asufficient quantity of starch to make the fabric properly stiff whensmoothed by the iron. I then take, say, one-third of any kind of cleanwhite soap where the fabric to be operated on is white; or, in case thefabric is colored, then a colored soap may be used, relying on thecoloring matter therein to assimilate with'and heighten the color of thefabric, in the proportion of one-third of soap, by weight, to two-thirdsof the starch, or in any other suitable proportions, to form a perfectlubricant when the iron is passed over the fabric.

The soap is dissolved. in the starch and thoroughly mixed therewith.

What I claim as new, and desire to secure by Letters Patent, is

A starch lubricant composed of starch and soap mixed together in aboutthe proportions set forth, the soap being of the same color as thefabric to be ironed, as andfor the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two Witnesses.

MARY E. ROBINSON.
